Two cars travel along a highway at the same speed.

Mathematics
1 answer:
Mazyrski [523]3 years ago
6 0

Answer:

30 mins

Step-by-step explanation:

<em>speed = distance/ time </em>

speed of car A

= 20/ 12 km/ min

= 5/ 3 km/ min

also, speed of car A = speed of car B

speed of car B = 5/ 3 km/ min = 50km / time taken (in mins)

\frac{5}{3}  =  \frac{50}{t}

5t  = 150

t = 30

=> t = 30 mins

PLEASEEE HELPPP its due in 10 mins PLSSS
Rufina [12.5K]

Answer:

About 525 times.

Step-by-step explanation:

You have a 5 in 8 chance of getting a consonant originally. You should try to find an equal ratio except with 840 as the second number. As of now it's      5/8 = ?/840

8 is a factor of 840 and if you divide 840 by 8 you get 105. If you actually think about it 105/840 would be an equal ratio to 1/8 so you multiply 108 by 5 to get 525.

Carmen measured a house and made a scale drawing. The scale of the drawing was 9 millimeters = 1 meter. What is the drawing's sc
malfutka [58]
When you write a scale factor, the units have to be the same.  In this case, 9mm on the drawing represents 1 meter on the house.  Change 1 meter to millimeters (1m = 1000mm).

9 mm on the drawing represents 1000 mm on the house.

The scale factor is 9 to 1000, or, as a fraction,  9/1000.

Becky and tommy are asked to solve -4x-25=8x+15 identity where one of them made an error
ololo11 [35]
I feel sorry for Becky and Tommy. The one who didn't come up with x=-10/3 made an error.

first bring 8x to the left and -25 to the right and simplify:

-4x-8x = 25+15 => -12x = 40

x = -40/12 = -10/3

Answer:

The answer to your question is Area = 49n² - 70n + 25    

Step-by-step explanation:

Data

Length of the side = 7n - 5

Formula

Area of a square = side x side

Area = (7n - 5)(7n - 5)

2.- Expand

Area = 49n² - 35n - 35n + 25

3.- Simplify

Area = 49n² - 70n + 25    

4.- The polynomial is 49n² - 70n + 25
